Emergency & Disaster Resources

If you or a loved one have been affected—or may be affected—by a hurricane, we can help. Review our comprehensive information and resources on emergency and disaster planning. We can also connect you to emergency shelters and other critical needs now, or other resources after the initial emergency has passed, such as temporary living assistance, medical equipment, medications, emotional support, or other challenges to your quality of life. Please call 1-800-344-4867 to connect with an MS Navigator, or via e-mail at generalmailbox@nmss.org.

MS Prevalence

Worldwide, MS organizations have estimated that 2.3 million individuals are living with MS.

Improving reporting

You can help improve the accuracy of MS prevalence reporting by joining the Society in our collective efforts to advocate for the establishment of a national registry that would track MS prevalence in the US by joining the Society’s activist network.

MS prevalence

Worldwide Prevalence: MS organizations have estimated that 2.3 million people are living with MS worldwide. However, in the U.S., there has not been a scientifically sound, national study of prevalence since 1975. Additionally, MS incidence and prevalence are not consistently reported or tracked in the U.S., and there is no government requirement to do so. In the absence of government-reported data, the National MS Society relies on scientifically-sound estimates of prevalence while we advocate for better and more systematic reporting and tracking at a nationwide level.

National MS Society study to develop a new prevalence estimate

To address the gap in prevalence estimates the Society launched the MS Prevalence Initiative with the goal of determining the best way to develop a scientifically sound and economically feasible estimate of the number of people in the U.S. who have MS. This initiative included leading experts in MS prevalence, who utilized administrative datasets from a variety of sources including Medicare, Medicaid, Veteran’s Health Administration, and private insurers. This scientifically rigorous approach was necessary to ensure an accurate prevalence estimate.

The Society’s progress in updating the estimate of multiple sclerosis prevalence in the U.S. is vital to the MS movement – both here and globally. Our increased understanding of the impact of MS on people’s lives, including the individual and collective financial impact of managing MS, along with the healthcare and services people with MS need, is essential. A scientifically sound prevalence estimate will help researchers understand if MS is increasing, or if there are MS clusters that may hold clues to factors that may trigger MS. Additionally, it will ensure the continued acceleration of crucial research to ultimately find treatments and solutions for each person living with MS.

Preliminary results of the study estimate that nearly 1 million people are living with MS in the U.S., which is more than twice the previously reported number. The results were presented in October 2017 at ECTRIMS — the world’s largest MS research meeting.

An important next step in confirming this prevalence number includes anticipated publication in a prominent medical journal. Publication is expected in 2018, The final results will be broadly communicated as another important tool in accelerating progress toward achieving a world free of MS.

Other related National MS Society work

A National Neurological Conditions Surveillance System through the Centers for Disease Control and Prevention (CDC) was authorized through the 21st Century Cures Act.

The Society, and MS advocates nationwide, advocated for the inclusion of the System in the 21stCentury Cures Act to track and collect data on the epidemiology of neurological conditions. It is authorized for $5 million a year from 2018-2022.

Now that the System is authorized, MS activists and others with neurological conditions must advocate for funding for the CDC to create and manage the System.
